Izu Islands, Japan — A magnitude 4.6 earthquake struck the Izu Islands region of Japan on Friday evening, according to the U.S. Geological Survey. What happened: The quake hit at 10:14 PM CT on Friday, October 30, centered in the Izu Islands region at a depth of about 10 kilometers (roughly 6 miles). The Izu Islands sit south of Tokyo in the Pacific Ocean, an area where earthquakes are common. Impacts: No tsunami warning was issued for this quake, and no damage reports were available at the time of this report. Shaking in the island chain would have been felt most strongly near the epicenter, with lighter shaking farther away. What to do: Drop, cover, and hold on during shaking, and stay away from windows and heavy objects that could fall. After the shaking stops, check yourself and those around you for injuries and watch for hazards like broken glass, damaged walls, or gas leaks. Stay alert for aftershocks, which can follow in the hours and days after a quake, and be ready to drop, cover, and hold on again. If you are near the coast and feel strong shaking, move to higher ground right away and follow local emergency instructions. Source: U.S. Geological Survey (USGS), October 30, 2026.
